Re: Using Bootmem for large DMA buffers in the presence of the slab allocator

From: Christoph Lameter

Note also that allocating a 64M buffer will be difficult due to the
maximum allocation size restrictions of the page allocator.

You therefore have no choice but to allocate the memory at boot
time. Or (if you have control over the arch) increase the maximum
allocation unit (MAX_ORDER I believe).
